1993 Ford Mustang Two Wheel Drive Automatic 124000 miles

my 1993 ford mustang is throwing two codes

1. 223 loss of dual spark (DPI) control
2. 224 erratic ignition diagnostic monitor (IdM) input to processor

I cant find any books that tell me where to start to trouble shoot these codes.

Thanks for that info.

Code 223 indicates Loss of Dual Plug Inhibit (DPI) control (dual plug (EI)

Code 224 indicates PCM detected coil 1, 2, 3 or 4 primary circuit failure (dual plug EI)

Below are the testing procedures for each code:
